My 1440p monitor died on me so I’m looking to upgrade to a 4K monitor, to be used with my home+work laptops, some older game consoles and an aging Linux PC.
The aging PC is the problem: it’s an i5-6600 on an Asus B150M-A. It lacks DP and its HDMI port can’t do 4k60.
I vaguely recall there being super cheap graphics cards meant for exactly this sort of thing, just a low end GPU with a bunch of ports, but I can’t seem to find much, especially not AMD (Linux + Nvidia remains meh)
Suggestions? Perhaps a minimally invasive upgrade to the PC? Or just stick it out at 1440p (non-integer scaling, ugh) until I can upgrade properly?
- Any GPU made in the last 10 years with will have displayport 1.2 which will do 4k 60. That’s Radeon 6000 series (2010) or Nvidia 600 series (2012) - Just browse FB marketplace, or your local used junk suppliers and sort by price low to high. New low end GPU prices are insane, don’t spend that money on them. 
- I think the most bang for your buck would be the Arc A380. 4 displays, 8k60 and AV1 acceleration. Not sure how good the linux support is but the drivers aren’t closed source like nvidia so I imaged it’ll be decent. - There’s always AMD ofc but I don’t think the 9000 series does anything special IO-wise. Might as well look at the cheaper 7000 series 
- If your PC is that old and bad, why don’t you just use your home laptop instead?
